Abstract

Infectious Phenotype The pathogenic yeast Candida albicans needs to adopt a filamentous form to invade tissues. The distantly related yeast species Saccharomyces cerevisiae also takes on a filamentous form for nutrient foraging. Comparing genome-wide deletion libraries between the two species, Ryan et al. (p. 1353 ) identified genes involved in three different filamentous yeast phenotypes and found unique genes for each of these phenotypes. However, in addition, core genes, including a previously unknown conserved regulator, appear to have homologous roles in regulating filamentous growth in these distantly related yeast species.
